Yes, I considered this. In fact, if there is consensus that FAT should
be excluded, I'd add another category to the configuration parameters
of the locate.updatedb script. Currently there is:

	$SEARCHPATHS	(start points for the directory scan)
	$PRUNEPATHS	(sub-trees to exclude from scanning)

	$FILESYSTEMS	(file system types to include)

and we could add:

	$PRUNEFS	(file system types to exclude)

with the latter overriding $FILESYSTEMS ...

As you may know, the new default for $FILESYSTEMS is all local,
non-synthetic, non-loopback, principally writable file system types
(which include msdosfs). The $PRUNEFS could be used to drop a few
that could be scanned, but where it is still not desirable.
